Influence of Fire and Trapping Effort on Ground
Beetles in a Reconstructed Tallgrass Prairie

Kirk J. Larsen and Jason B. Williams


Abstract: The effects of fire on communities of ground beetles (Coleoptera: Carabidae) were investigated between 9 April and 28 October 1996 in Anderson Prairie, a reconstructed tallgrass prairie in Decorah, Iowa. We collected ground beetles in pitfall traps from prairie plots burned in the spring of 1994, 1995, or 1996. We collected a total of 1,772 beetles representing 45 species. Recently burned plots (burned in 1996) had a lower diversity and evenness of carabid assemblages than plots burned in 1994. However, species richness was greatest in the most recently burned plots. Short-term sampling, consisting of three one-week exposures during the peak beetle activity period, yielded similar abundance, species diversity, and evenness trends to biweekly, full-season sampling.

Key words: Carabidae, Coleoptera, fire, pitfall traps, tallgrass prairie.
